ADJUSTABLE SWINGING SPRAY FOR MINERAL-WASHING.

Specification of Letters Patent.

Patented Jan. 5, 1915.

Application filed March 23, 1914. Serial No. 826,486.

' To all whom it may concern Be it known that I, WILTON E. DARROW, a citizen of the United States, residing at Sutter Creek, in the county of Amador and State of California, have invented certain new and useful Improvements in Adjustable Swinging"Sprays for Mineral-Washingyand l dodeclare the following to be a clear, full, and exact description of the same, suchf'as willenableothers skilled in the art L to which it appertainsto -make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which" form a part of this application.- p

This invention relates to improv ements in paraphernalia used in fc'o'nnect'ion' with the concentration of slime crushed ores, the'bb ject of the invention being to produce a spraying means for washing 'oa'andcollecting the valuable mineral concentrated.

fl'hejdevice is particularly des gned for usewith a'plurality of sprays arranged in serie'sfone above the other, as shown in fatents No sl 89eQ33l'arid 9 06,2043, dated b'eptemheifclth, 1908 and Decemb'er 8th, 1900', re-

speetively, or, in"devices of a similar type,-

and theaim ofnmy' present invention is to produce such" arspray as will wash over the table and at the same time moveup and down with respect to the grade of the trays in 'oi'der'to fully cover the entire surface of the trays with water and in such a ma nne'r as to remove the accumulated mineral as fast as the rotation of the concentratmg device brings the loaded surfaces of the trays past the spraying zone.

A further object of the invention is to produce a simple andinexpensive device and yet'one' which will'be exceedingly ell'ect'ive for the purposes for which it is designed.

disposed in an inclined manner with respect to the concentrating trays z and Jouriiaied at its top and bottom to allow or a rotary motion.

rro ecting from a point near the bottom of the post i is a pipe 5 having a nexihie connecting hose l ior connecting it with any SlllLzlUle water supply. All the outer end or said pipe is is a bull and socket oint 5 by means of which a vertical ulpe U is connected with the pipe 5 which projects at substantially right angles to the ipe 0 and parallel Wltll tlltfi vertical plane in. tile trays :4, said pipe 6 ueingournaieu at its upper end, as at l, in a pluJfictlllg arm 0' SWlHzlUtl at its other end as at :1, which arni 25 pro- Jects in aparallel manner w th respect to the p pe 3 101' the 'pur'pose'oI maintaining the pipe-o in a Substantially vertical position at all times irrespective of its movement hereinafter described... Un the upper end of the pipe is a pro ectingarin lu Ior a purpose as will presently appear.

Communicating with the pipe'6 are a plurahty of independent spray pipes 11 each pro ecting over one of the trays 2 and'being provided with one or'more discharge nozzles 12. 1' 1 Connected withthe pipe 6 are a pair of rearwardly PIOJQClZlllg arms 13 into which hook pitmen la, eachof said pitmen being connected with a crank 15, such cranks 16 being mounted on a shaft 16 having a driving pulley 17 for connection with any suitable motive power. I

The connections of the pitmen 14: with the cranks are made adjustable by such pitmen having a plurality'of holes '16 to receive bolts 19 by means of which the pitmen may be connectedwith the "cranks at dilferent points as will be readily seen.

The numeral 20 designates a rod adapted to be connected with the arm 10 and fixed at the other end at any desired point such as at 21, all for a purpose as will presently appear.

in practice, water is admitted through the member 4: or members 3 and 6 and the same passes out through the members 11 to the spray nozzles 12 which discharge upon the trays 2. In order to thoroughly wash the trays it becomes necessary to give these nozzles 12 a swinging motion and at the same time a slightly upward and downward motion over the surface of the trays and this is accomplished as follows, namely: Presuming the rod 20 is not connected with the arm 10, rotary motion is imparted to the pulley 17 which drives the shaft 16 and the cranks 15 to operate the pitmen 14. The post 1 then forms a pivot upon which the entire spraying mechanism swings and swinging on that point and its own end bearings, the pipe 6 would move in an are described substantially by the line a shown in Fig. 2, which movement by reason of the inclined position of the member 1 and the position maintained for the member 6 by means of the arms 3 and 8 would cause the spray nozzles 12 to move up and down over the trays 2 and at the same time describe a motion over the surface of the trays 2 substantially the same as that designated by the line b in Fig. 2. When however it is desired to move the said spray pipes 11 in a fixed arc, the rod 20 is connected with the arm 10' and with its fixed point 21 which will cause the rod 20, the arm 10 and the arms 8 and 3 ally to swing in the same are with the member 1 as their pivot which will then cause the spray nozzles 12 to move over the surface of the trays 2 in substantially the arc desig nated by the letter c in Fig. ,2.

From the foregoing description it will readily appear that by means of my im proved spraying mechanism, I can spray theentire surface of each of the trays 2 with a very short movement of the spray pipes 12 over the surface thereof which can be adjusted as desired by increasing or decreasing the number of spray nozzles 12, the idea being to keep a continual spray against the surface of each tray from the extreme upper end to the extreme lower end thereof in order to thoroughly wash the valuable slimes therefrom.

From the foregoing description it will readily be seen that I have produced such a device as substantially fulfils the objects of the invention as set forth herein.

While this specification sets forth in detail the present and preferred construction of the device still in practice such deviations from such detail may be resorted to as do not form adeparture from the spirit of the invention.

Having thus described my invention what I claim as new and useful and desire to secure by Letters Patent is 1. A device of the character described comprising the combination with a concentrating table, of a spraying means mounted upon an axis, and means for reciprocating the spraying means longitudinally across the table and means for causing it simultaneously to describe an arc laterally with re spect to the table, as described.

2. A device of the character described comprising the combination with a concentrating table, of an inclined spindle, an arm on such spindle, a vertical member projecting upwardly from the outer end of said arm, said vertical member having an independent movable bearing at its upper end, spraying members projecting. from said vertical member over the surface of said table, as described, and means for oscillating said spindle.

3. A device of the character described comprising the combination with a concentrating table, of a spindle, an arm mounted on said spindle, a vertical member on said arm, an independent movable bearing on the upper end of said vertical member, a rod flexibly connected with said arm at one end and at an independent point at its opposite end, a spraying means mounted on said vertical member and projecting over the surface of said concentrating table, and means for oscillating said spindle as described.

In testimony whereof I affix my signature in presence of two witnesses.
